Review Comment:
I don't think it's unreasonable to expect the caller to have to allocate
enough space - that's pretty normal. Especially for an integer value - the
maximum possible length of string isn't that long.
If you do want to have this allocate space itself, consider having the
length of the string passed in as a pointer the way that `dest` currently is,
and having it return the newly allocated string. That way there won't be any
chance of somebody passing something un-freeable into the function.
